CentOS 7 Cloud 16.0.4 Nova Security Update

Hello,
A security issue has been found in Nova 16.0.3 and a fix has been released in December, however I haven’t seen Nova 16.0.4 in the Cloud repositories yet. Is someone working on updating the nova packages?

Sharing Software Collections over NFS?

It's been a while since I wrote an article about a cool feature that we
introduced together with Software Collections packaging format, which is
*the ability to share the environment on multiple machines by NFS
sharing *[1].

The idea is very simple -- install Software Collections of your favorite
application stack (say Python 3.6 + NodeJS 8) and mount the /opt/rh on
workstations.

Some way to validate SIG repo repodata (via HTTPS or GPG-signed repomd?)

Hey,

I've been trying to get the CentOS SIG repositories enabled in the
openSUSE Build Service[1].

Today, I started working with Adrian Schröter (who is CC'd to this
email) on getting this done, and the issue right now is that there's
no way to securely validate the repodata.

OBS supports two ways:

1. Validating repodata from a mirror using the copy on the master
server fetched through HTTPS.

Hello CentOS users,

in the recent time I keep getting the logwatch warnings from my 2 dedicated

I guess because of the numerous kernel updates (because of

Could someone please suggest me, which files in my /boot partition would be
safe to delete?

Issues with NVidia video driver and CentOS

I'm having issues with a quad video card on CentOS.

We have several systems on CentOS 6.8 and CentOS 6.9. The installed
hardware is:

Video card - Nvidia NVS quadro 440
PC - Dell OptiPlex 9020

Whenever you update the kernel, it kills the graphical interface. The
system appears to lock up and freeze during a reboot, but you can still get
into it with SSH, or, if you're at the console, control-alt-F2 gets you to
a command prompt.

If you exclude the kernel update when applying yum update, it is usually
fine.

CloudStack publishing effort in CentOS

Hi all, (/cc cloudstack-dev)

I'm Rohit Yadav, committer/pmc from the Apache CloudStack [1] community.
Apache CloudStack is an IaaS cloud computing platform.

I've been maintaining and publishing the CloudStack noredist repos [3][4]
for few years now, and I would like to get them published to the official
CentOS (and other distros) repositories.

I met Rich during Fosdem yesterday and he suggested to reach out to the

Software does not boot in Secure Boot

The matter of EUFI’s Secure Boot vs Legacy Boot has been briefly discussed a couple of days ago. I would ask the List opinion concerning our case.

A bit of the history. We’ve been in the research of malicious hypervisor threat since 2013. We finally developed publicly available HyperCatcher freeware. It runs on specially built Ubuntu 14.4. We tried CentOS 6/7 as well. The OS was compiled to minimize the number of services and OS features to only essential to the application. The software is ISO bootable image.

The problem.

In reply to: What is best way of managing isolated network environment?

(Couldn't find the original request in my email but definitely have an idea).

Set up an OpenVPN server on your network and create a client on the isolated network (set up to connect on boot), configure routing appropriately. You get to decide what subnet the VPN IP address is on, in this situation I recommend a static IP address for the client. From your network you connect to the OpenVPN IP address and connect to the rest of the isolated network from it (or set up multiple clients on the isolated network).

How is initrd.img packed and compressed?

Hi,

In order to work around a known upstream bug I needed to add a udev
rule to pxeboot initrd.img on CentOS 7.

The process is straightforward:
1 - extract the pxeboot initrd.img to a new directory
2 - add the udev rule needed to fix the bug
3 - pack and compress it back in initrd.img format

The resulting updated image works, it fixes the upstream bug and life
is good. But although it works, it's not
the same format as the original initrd.img that ships with the distro.
I would like to know the proper incantation
used to package initrd.img

Now for the specifics.

What is best way of managing isolated network environment?

Hello,

We need to manage isolated network environment so that even though host name and ip address could be same, but they are located in isolated network environment so that’s not a problem. However, that would be very challenging to build a server in such an isolated environment. For example, we could do kickstart to build a server in non-isolated network environment, but for isolated one, we don’t have such a kickstart server. If we had such one, that would mean we consume more resources for building server.

systemd-udevd not applying ATTR to block device at boot

Hi everyone,

I have a udev rule file that contains a singular rule:

SUBSYSTEM=="block", ACTION=="add|change", ENV{ID_VENDOR}=="*Google*", ENV{DEVTYPE}=="disk", ATTR{queue/scheduler}:="noop"

When I use a Google Cloud instance and boot it, things work as expected and /dev/sda (a persistent disk) uses the noop scheduler. If the instance also has a Local SSD type disk, however, the change in scheduler is not applied. This is a bit academic, because the Local SSD device uses noop by default (somehow, I don’t see any udev rules for setting this outside of my own).

Xen hypervisor on CentOS 7.4 with modern UEFI server not booting from grub

Hi,

I installed CentOS 7.4 on a modern Lenovo ThinkSystem SR630 server

Unfortunately when I reboot after having installed the xen package the

Why is the line "+auto.master" present in the /etc/auto.master file? Does this not create a loop, and perhaps is the reason why, on every boot, I see the message, "automount[3260]: problem reading master map, maximum wait exceeded"?

This is in an unmodified /etc/auto.master from autofs-5.0.5-133.el6_9.x86_64 in CentOS 6.9. The only other non-comment lines in that file are:

failure to start httpd after today update

Hello,

I ran today update of my CentOS 6.9 running on Dell T105 (AMD OPTERON) and httpd failed to start. Any idea what could cause that? I never had a problem after CentOS 6.x update. Web server runs since March 2017. I do updates usually once in a week.

Thank you

Document/collaboration server advise needed

Dear All,

Three groups of scientists need to write documents collaboratively. They
are going to use MS PowerPoint, Word, also store PDF files. They want to
be able to add external people from other groups they collaborate with
and give them access to some areas or "projects". In other words, they
want some collaborative work environment, mostly to work on documents.

In the past scientists were using TeX, and one of version control
systems (CVS, subversion,...).

repodata out of sync for centos6-updates

Hi,

I wanted to update the bind package on our centos-6 servers, and the
package is there for the mirrors I've checked, but the repodata dates
back from January 18. May be I'm too fast and the repodata update comes
later. If so how long can it take?

Cheers, Christian.

virt-manager change to bridged networking on CentOS 7.4

Hi All,

I have virt-manager running just fine currently using NAT.

I want to "change" it to bridged network. The GUI is not letting me change
anything on the network section.

How do I change it to be bridged ?

Thanks,

How to upgrade CentOS 6.9 KVM host to 7.4.1708 and not re-install guests

I have a Windows 7 KVM guest running on a Centos 6.9 KVM host. I would
like to upgrade the host system to CentOS 7.4.1708 without having to
re-install from scratch the KVM guest. What procedure should I use to
move the guest off the host system, upgrade the CentOS version and then
move the KVM Guest back to the host? For example, Is there a recommended
way to move the KVM Guest to a USB stick and then move it back to the
upgraded host? Thank you for your help.

An rpm specfile quesstion

I've built an rpm package to distribute an executable and datafiles, but I
need to link to the executable, with the symlink with a different name,
into /usr/sbin/

If I make the symlink in the %post, it doesn't show if you do rpm -ql, and
/usr/sbin/link gives "not owned by any package".
